摘要

分析了太湖流域典型城镇-常州市武进区地表水和5类排放源（市政污水处理厂进、出水，工业污水处理厂出水，分散式工业废水和水产养殖废水）中5种挥发性卤代烃的浓度水平，通过密集采样点设置的全年采样，揭示了地表水中挥发性卤代烃的污染特征，探讨了排放源对地表水的影响，初步识别了主要污染源.结果表明，地表水中目标卤代烃的含量在

Abstract

In this study, the concentrations of five VHHs in surface water and five differentsources of VHHs pollution (influent and effluent of municipal wastewater treatment plants (MWWTPs), effluent of industrial wastewater treatment plants (IWWTPs), wastewater from industrial enterprises and aquaculture) weremeasured in Wujin district, Changzhou, a typical town in Taihu Basin. The pollution characteristics of VHHs in surface water and the likely main contributor of VHHs pollution were determined by intensive sampling in the investigated regionacross four seasons. Results showed that the concentrations oftargetVHHsranged from<LOQ to 13.86μg/Lin the studied surface water samples, among which trichloromethaneand trichloroethane were found to be the most and least dominant VHHs in terms of their detection frequencies and occurrence levels, respectively. The annual mean concentrationsof VHHs in all the emission sourcesexceptfor aquaculturewastewater were higher than that in surface water (2.10μg/L). Among the five investigated emission sources, the seasonal variations of VHHs concentrationsin IWWTPs effluent and industrial wastewater exhibited positive correlation relationship with those insurface water; therefore, IWWTPs effluent and industrial wastewaterwere proposed as the main contributors of VHHs contamination in the study region.
